PORTABLE VENTILATING OU'I'FIT Application filed March 19, 1928i Serial No. 262,608.

This invention relates to ventilating apparatus, and has reference more particularly to ientilating appliances of a portable character which are adapted for application to the windows of residences and other buildings to expel foul air from the interior or induce fresh air from the outside,'without involving any substantial altera-tion or defacement of the window structure.

A portable ventilating apparatus of the general type to which the present invention belongs is disclosed in patent to Breidert and Starks, No. 1,549,440, dated August 1,1, 1925, and my present invention is in the nature of an improvement on the article of the said patent, one of the objects being to provide a more secure mounting -for the panel carrying the fan and motor on the window frame, and another object being to provide an improved adjustable closure strip to span the space between theI lower edge of the panel and the top of the lowered upper sash.

Further objects andattendant advantages of the invention will be apparent to persons skilled in the art as theV same becomes better understood by reference to the following detailed description, taken in connection with the accompanying'drawings, wherein I have illustrated a practical Aand approved embodiment of the invention, and in which- Fig. 1 is a front elevation of a window frame showing the upper sash lowered and my improved ventilating outfit. applied thereto; o

Fig. 2 is a Vertical transverse section showin the upper sash in raised position;

ig. 3 is a Vertical transverse section showing the up er sash in lowered position and the free e ge of the closure strip resting thereon;

Fig. 4 is a 'Vertical section, broken out, in the plane of one of the panel supporting strips;

Flg. 5 is an enlarged perspective det-all of the extensible closure strip, showing the under side thereof;

Fig. 6 is a perspective detail of one of a pair of push and pull rods for raising and lowering the upper sash;

Fig. 7 is a perspective detail of a braeket detachably engaged by the push and pull rod of Fig. 6;

Fig. 8 is a-sect'ional detail illustrating the function of spacers on the free edge of the closure strip to insure olearance between the latter and the top bar of the sas'h when the latter is lowered. I r

Referring to the drawing, 10 designates the top bar and 11 the side bars of a conventional window frame, and 12 and 13 designate respectively the (low sashes. 14 designates a rectangular panel con'veniently made of Wood and formed with a central hole 14' in which is mounted an annular frame member 15 formed with radial arms 16 and a ring 17 in which is su ported an electric motor 18 Operating a rect driven ventilating the upper sash 12 is lowered. as shown in' F ig. 3. i

The panel 14 is supported in working position by means of a pair of metal strips 20 formed on their lower ends -with upturned hooks 21 that support the lower ed e of the'- panel, as clearly shown in Fig. 4, an on theirl upper ends with downturned hooks 22 which overlap the upper edge of the panel. The downturned limb of the hook 22 is formed withlan upwardly turned or reentrant terminal portion 22' that bears against the outer face of the panel 14, and the downturned port-ion of the h'ook has a tapped opening to receive a thumb-screw 23 which bears against the npturned or reentrant portion 22' and forces the latter tightly against the panel. By this means the upper portion of the panel is held tightly against the window frame, and by retracting the thumb-screws 23the panel may lbe readily entered endwise into, and

upperand lower win- ILLINOIS, ASSIGNOB '1'0 ILG ELECTRIC VENTI-I- ILLINOIS, A CORPORATION OF LOUISIANA fan 19 which serves to move air through the ring frame 15 when withdrawn from, its supporting brackets in an obvious manner.

When the sash is lowered, as shown in Fig. 3, in order to enable the fan to function efliciently it is desirable to close the opening between the lower edge of the panel and the top of the lowered sash. Strips for closing this opening are broadly old, and two forms of such closure strip are disclosed in the reidert and Starks patent hereinabove idenoyerhang the side the extension members I end of the latter, said spacer strip tified, but my present invention einbodies certain improved features in such a closure strip which will now be described.

The panel 14 in practice is made wide enough to serve the widest window of aiiy dwelling or room in which it may be used, and wlien applied to narrower windows, can

franie members of the lattei', if necessary, without interfering with its proper functioning. The closure stri liowevei', must be adjustable lengthwise to 't tlie widtli of the particular sash With which it cooperates, and for this purpose the closure strip consists preferably, as best shown in Fig. 5, of a Sheet-metal plate 24;` with inwardly folded marginal fianges or lips 2.5 and 26 oii its lower aiid upper edges respectively. To the lower edge of the strip 2A are seciii'ed liinge members 27 that are attached `to the lower edge ofthe panel 14. Slidably engaged with the langes or lips 25 and 26 of the inain panel member 24 are adjustable slieet-metal extension members 28. Two, or only one, of 28 may be einployed, depending upon the width of the window to be served, and the member or members 28 and the main member 24 are so adjusted that their combined length will equal the width, between the sash grooves, of the upper sash 12.

As the upper sasli 12 is raised and lowered, the free edge of the closure strip rides over the stiles of the sash, and where one or both extension pieces 28 are employed7 it is necessary to provide means for preventing the fianged free edge 23 of the closure strip from striking the top cross-bar of the sash as the latter is being lowered. For this purpose I employ a spacer conveniently consisting of a bowed metal strip 29 that is attached at one end to the under side of the closure strip extension 28 at or near the outer 29 sliding on the stile of the sash in the manner shown in Fig. 8 and holding the free edge 26 of the main member 24: of the closure strip siifliciently spaced from the path of travel of the top cross-bar of the sash to prevcnt any interference with the latter.

'Vhen employing a ventilating panel of this Character which, when in place, covei's the major portion of the upper window sash, it is desirable to provide means for conveniently raising and lowering the upper sash without having to first remove the panel. As a convenient means for this piirpose I preferably einploy on each side of the upper sash a pair of push and pull rods 30. The upper end of each rod is bent to form ay hoolr 31 adapted to detachably engage with a horizontal U-shaped bracket 32 mounted on the upper end of each sash stile, as shown in Figs. 1 and .2. The Vertical limb of the bracket and its upper horizontal limb are provided with holes 33 and 34 respectively, through which the hook 31 may be succesthe push and pull rods 80 are eniployed, the

spacer or spacers 29 on the free edge of the closure strip may be omitted, since the free edge of the closure strip rides on the rods 30 and the latter serve to prevent collsion of the free edge of the closure strip with the top bar of the sash in lowering the latter. This feature is not claimed herein, but forms the subject matter of a divisional application, filed May 15, 1930, Serial No. 452,535.

I have herein shown and described simple and practical einbodiments of the novel features of the inventioii, but do not limit the latter to the exact forms and structures shown for pu rposes of illustration, but reserve such variatioiis, modifications and mechanical equivalents as fall within the spirit and pur- View of the claims.
